That's a crap platform for buying and selling Bitcoin, the app which is a crypto wallet allow you to meet other people in the zip code your provided just for trading? How come I am the only one thinking how dangerous this is? , it a not even safe because location can one way or other be revealed, since this app is using Zipcode it's a red flag.

I have been using Binance Exchange peer-to-peer feature for a very long time now and there's no need for anyone to know the location for the zip code of seller, all you have to do is provide your bank details where you will receive your payment and Binance will release your crypto asset to the buyer after you have confirmed that you received the fund.
